Nut upsuser - Mar 2023 - APC 1000 NUT stops responding

Good afternoon,

So been trying to figure out a problem i am encountering with NUT and 
two APC 1000 UPS's that's connected via USB, First off it somewhat works
well kind of, Pull the power to either UPS and it's slow at responding 
but finally detects it however the other problem is that after a few 
days NUT just stops reporting that the Power has been off. Here is what 
I've noticed it starts working again once i reboot but the Web Gui I've 
configured is still updating, Pull Power no notifications via NUT but 
the Web Gui show's that the UPS is on Battery.

So there are two problems I need to fix, Delay on detection which is 
around 5 to 10 seconds before it detects that the UPS is on battery,

Second problem, when UPS's are on Battery it does not report it in 
console neither sends a email but Web Gui detects that UPS's are on battery.

Anyone have any ideas? I have tried what was suggested to try pollonly 
flag but doesn't make any difference. Both UPS's are plugged into a RPi 
4 via USB3 Port, I have tried Ubuntu Server and Debian but problem still 
happens

Regards

Jack

This is normal in my experience. UPS response time is in milliseconds, but  
it may delay reporting an "on battery" status in order to avoid
raising a
ruckus for temporary power blips.

I would try straceing upsmon, to see what it does, and fails to do.
